FUNCTIONAL DESCRIPTION

RFC Frequency Control

Characteristics

The cutoff frequency (fc) is controlled by the resistor connected to RFC pin (RFC). The characteristics about fc

versus RFC is shown in table 1.

Adjustment methods

It can set up by the following methods. Since resistance affects cutoff frequency, please use a high precise

thing.

I

Fixed resistor

The frequency can be adjusted using an external resistor connected to RFC.
